Information on the ability of the substance to biomagnify in the food chain, where possible expressed by biomagnification factors or trophic magnification factors.

Specifically, the full scale value of the current range selected multiplied by the crest factor of the meter (for current) must be greater than the peak current reading from the oscilloscope.

For example, if a watt meter has a crest factor of 4, and the current range is set on 3 amps, the meter can register current spikes of up to 12 amps.

The most important gaps in knowledge concern : 1) transfer and degradation processes (a better understanding and quantification of the fundamental transfer processes by which dioxins and PCBs move between the different environmental media and of the degradation processes occurring within these media is needed); 2) bio-accumulation and bio-magnification processes; 3) domestic incineration of wood (there is an information deficit concerning the amount and the composition of wooden fuels used for room heating and cooking purposes); 4) reservoir sources (the contribution to human exposure, the behaviour and degradation processes and decon ...[+++]tamination methods require examination); 5) open uses of PCBs; 6) carry-over rates and transfer factors for dioxins and PCBs from soil and feed to animal tissues and products (milk, eggs).
